My dryer beeps frequently while in use, and either does not heat at all, or heats for a very short time.

I looked up manuals to find the procedure to get the error codes, however, the code I am given after following the steps is not listed.

The instructions were:Turn the cycle selector knob to the 3 o'clock positionHold the select and pause/cancel buttons simultaneously for 6 secondsHold the start and pause/cancel buttons simultaneously for 4 secondsTurn the cycle selector knob to the 2 o'clock position and count the beeps of both the 4 indicator lights and the start button.
